RETAINING DEVICE FOR SLIDE FASTENERS Filed Jan. 8, 1952 Patented Oct. 27, 1953 UNITED STATES PATENT oFFicE David E. Wilson, Arlington, Va. 7 Application January 8, 1952, semi No. 265,373

2 Claims. (Cl. 24-20511) This invention pertains to retaining devices for l slide fasteners, and relates moreparticularly to a device for preventing themoyement ofa slider after it has performed the function of fully closing the conventional interlocking slide fastener structure, in the placketof dresses, flies in mens trousers, and other openings in garments where interlocking fasteners are used. There are numerous forms of slider locking devices proposed and in use, someof which are comparatively simple in design and very efficient as long as they remain new. The greater portion of slider locking devices are carried on the slider member or engage locking. means, at the top of the conventional interlocking slide fastener structure and are subject to constant wear from daily usage and often causes trouble due to difliculty of operation. This means that the wearer of a garment having the slide fastener. is confronted with a situation in which he can no longer depend on the satisfactory working of the device andis compelled to go to the expense of replacing the old damaged slide fastener with a new one.

It is therefore an-object of this invention to provide a simple constructed retaining device for slide fasteners designed to hold the slide fastener in its fully closed position, usually at the top of the placket or garment opening, at the same time permitting the intentional movement of the slide fastener along the slide fastening structure when it is desired to open or close the garment opening.

It is a further object of the invention to provide a retaining device for sliders that may be permanently attached to the conventional pull-tab of a slide fastener and that may be used to pull the slider open and closed, and that may be attached to the waist band of a garment to provide a positive holding means and prevent unintentional movement of the slide fastener from the closed position on a garment.

i It is a further object of my invention to provide a retaining device for slider fastening devices that can be manufactured cheaply. by a simple stamping process with a minimum of bending to form a complete single element, having thecoin- Joined function of holding the ends of the fastener device together and retaining the slider in closed position. q

It is a further object of my invention to proe a. i r. etei iined i s that can be Dermanently. attached. to theconventional form of slide fastener and perform the equivalent in service as provided by the self-locking more costly type of slidefasteners, and also convenient to readily transfer from one garment to another should occasion require.

Another object of theinvention is to provide a retaining device for slide fasteners that can be cheaply stamped out and made substantially in one working process of suitable material such as .stainless steel, aluminum alloy, nonferrous metals or plastic material, which is durable and well adapted to withstand the rough usage to which it may be subjectedin every day use on a garment.

With these and other difliculties in mind it is an object of my invention to produce a retaining device for slidefasteners whichis easy touapply tothe pull-tab of a conventional interlocking slide fastener structure. and which when applied will positively remainin permanent engagement at alltimes with said pull-,tab,'also to provide means for securing said retainingdevice togthe waist band ofa garment, and securely holding the slide fastening device in top most position. of its travel on the slidefastener structure thereby providing positive means. against movement of the sliding device.

With these and other'objects in view the invention will now be described with reference to the accompanying drawings andiwillbe pointedout 1n the appended claims. In the accompanying drawings, I have shown one embodiment and two modifications thereofwhich my invention may assume in practice. In the accompanying draw.- 1 s- Fig. 1 is a perspective view of the retaining device for. slide fasteners. as applied to thefly of a pair of trousers, showing the position of the device on a waist band and its manner of engaging the pull-tab when the slider is in fullclosed position.

Fig. 2 is a similar view showing theretainlng device attached to the slide fastener and removed from the waistband of the. trousers which" are in partly open position.

F g. 3 is a perspective view of the retaining device fora. slide fastener showing the front and rear wing members-and the attaching: hook for engaging the pull-tab on the slide fastener.

Fig. 4 is a plan view in blank form; showing dotted lines A- and B, indicatingthe bending areas to form the complete single device.

Fig; 5 is a'sectional view taken on line-V"-"-V ofFig.-1.

Fig. 6 is a sectional viewtaken on-line VI--VI of Fig. 1.

Fig. '7 is'a perspective view of a modified form of the retaining device showing---an-elongated opening inthe front wing, to facilitate use of 'the device where snap fasteners are used to close-the arment band.

Fig. 8 is a perspective-viewer a modified form of the retainmg'device usingplastic as amedium to form the body of the device, showing metal hook attached toplastic body. Fig. 9 is a' sectional view takenonline VlV- VIV of Fig. 8, showing themanner of attaching themetal hook to the plastic front wing oi -the device. 'In the. accompanying .drawing...I. have .shbwn for purposes of illustration one 'embodimentand two modifications thereof which my invention may assume in practice. In the preferred form I have shown the invention attached to the fly of a pair roi itrousers as.shown-'-in;l igs. 21 and although ithe device :is equally adaptable for use in the plackets of dresses, openings in corsets or girdles or other forms of wearing apparel.

Referring more particularly to the drawin in which similar reference characters identify similar parts in the several views, I havewshown in Figs. 1 and 2 a fragmental view of a pair of trousers consisting of waistband 10 attached to a garment in the usual manner, arfiy 1:2 ,to which is stitched a conventional interlocking slide fastener structure "I4. The retaining device "for the slide fastener which 'I,shal1,desig hate as a whole, as 16, comprises a'front wingl.8

and a back wing and an'integral neck portion 22 forming the body of .the retaining device. The integral neck member 221by virtue of its resiliency when engaged withthe Waist .band .113. causes I the front wing, member l 8. and the .back Wing memberifl totightly clamp on the waist band in a mannertosecurely holdrtheretaining device' in; position. on .the waist band.

In Fig. 8 of the drawing I have shown another modified form of construction in which the device is formed of thermoplastic with the aperture 4,6 shownin ovalshape-in thefront wing 18, to fitJaroun'd the fastening button 40. The hook 3 B is of metal and isprovided with an extending member 4 8 which extends through the lower portion of the'front wing member and is bent downward at '50 to "form a fastening means against displacement a shownin Fig ii of-the drawing.

It may be noted that "I have made-reference to the ffront wing and rear wing and neck of the retaining device for slide fastener and have usedthe expressions as a convenient way of designating the relative location of the various parts,-it will be obvious that the'termsare used'in reference tothe position of" the partsfls 'disclosedin' the accompanying drawings and are not intended as'limiting expressions. It should be further understood that any suitablematerial may be used inthe manufacturing of-the retaining device for slide fasteners, and that-any variations in the shape and relative arrangement of the, parts such as. come within the-scope of the claims appended herewith are to be regarded a Jformingpartof my invention.
